[Plone-IT] Non riesco a creare utenti in Plone

[Giampiero Lago]

Se cerco di creare un utente in Plone, tramite Site Setup -> Users and 
Groups -> Add New User

Mi da la maschera di immissione dell'utente poi, una volta cliccato su 
Register, sembra che l'operazione vada a buon fine
ma se lo cerco come utente non lo trovo, nemmeno riesco ad effettuare il 
login come quell'utente.

Ho porvato a mandare l'istanza in foreground per vedere se dava qualche 
errore ed e' uscito questo:
